The increase in staff costs, inclusive of capitalised costs, amounted to 9,413 thousand euros and was influenced by the partial release, in the first quarter of 2013, of the amounts allocated for MBO and bonuses for Executives and Middle Managers since the targets set were only partially achieved.

The change was also affected by the wage increase resulting from contract renewals in 2013.

With regard to capitalised costs, they posted an increase of 18,196 thousand euros, substantially attributable to the water companies, the networks segment and the Parent Company. This increase derives from the considerable effort made by Group personnel with respect to the Acea2.0 Project and the revision of procedures for capitalising internal costs.
